Hardware resources 4 Hardware resources To use all hardware resources in a program, the device must be configured. The configuration is carried out in ALP and is transferred as a part of user project to the device memory. The configuration parameters are stored in non-volatile memory of the device and are safe when the device is powered off. The device can also be configured with the function buttons via the system menu without being connected to ALP (sect. 5.2).
Hardware resources Fig. 4.2 Property Box for analog input See ALP Help for detailed information about analog input configuration. 4.1.1 Analog mode Configurable parameters: Input mode – select Analog Filter – filter time constant (0…60 s) Input signal – 4-20 mA, 0-10 V, 0-4000 ohm Lower limit – lower measuring limit Upper limit – upper measuring limit Decimal places – parameter DP for Modbus request (Table 4.2).
Hardware resources NOTICE If the input signal does not correspond with the hardware configuration, the device can be damaged. Check the positions of the jumpers XP1…XP4 before wiring. To configure the input hardware: – – – remove the front cover set the jumpers on the respective jumper block XP in accordance to the expected input signal using a thin tool (e.g. tweezers) close the front cover. Fig. 4.
Hardware resources To control an output, a value of type REAL32 within the range 0…1 has to be assigned to it in the program. When the value of 0.5 is applied to the output 4-20 mA, the output current will be 12 mA. When the value of 0.5 is applied to the output 0-10 V, the output voltage will be 5 V. See ALP Help for detailed information about analog output configuration. 4.
Hardware resources Fig. 4.7 Slave configuration in Slave mode Following parameters can be set for Master: Name – device name in the configuration tree Address – device address in the Modbus network.
Hardware resources Table 4.
Hardware resources PR200 as a master can control up to 16 slaves over one RS485 interface. Each slave can maintain up to 256 variables. To use the same name and the same address for different slaves is allowed. To add an interface, use the context menu of the node Interfaces in the configuration tree and select Add interface > RS485 (Fig. 4.9). Change the mode to Master in the right window part. Fig. 4.
Hardware resources Fig. 4.10 Slave configuration in Master mode Note: If PR200 is a master in the Modbus network, it is necessary to observe the following rules to speed up the polling of all slaves: 4.4 If one or more slaves are disconnected or not accessible, it is recommended to block the polling of these slaves in the program using the parameter Start query or to minimize the parameter Timeout for these slaves.
Hardware resources Fig. 4.11 Service mode jumpers RUN-STOP mode In RUN-STOP mode the execution of the program is interrupted. It can be useful if the system menu is unavailable, e.g. if the corrupted program leads to device malfunction. Set XP2 jumper to activate RUN-STOP mode. In RUN-STOP mode, a new program can be uploaded to the device. In this mode the device can be used only as a slave and the network variables are disabled.
Operation 5 Operation Once the program has been transferred to the non-volatile memory, the relay restarts. On startup, the relay performs a self-test. If it is unsuccessful, the relay will switch to error mode (sect. 5.1). Otherwise, the program will run (Fig. 5.1) WARNING The program is executed after it has been transferred to the relay. It is recommended to transfer the program before wiring the relay.
Operation Press button for 3 seconds to access the menu. Press button for 3 seconds to exit the menu. The menu can be password protected. The password can be set and changed in ALP or using the system menu. If the password is lost, it can be changed by loading a new project to the device. 5.2.1 Display navigation The display can be used in view or edit mode. The edit mode is only for editable display elements available.

Operation function button or of a variable. For further details about display programming, see ALP Help. For display navigation, see section 5.2.1. When assigning а jump condition to a function button, don't forget that the user function of the button has a higher priority than its system function, i.e. and buttons cannot be used to scroll the lines inside a display if they are used as the jump condition for it. akYtec GmbH · Vahrenwalder Str. 269 A · 30179 Hannover · Germany Tel.
